Lift up the distributor cover slightly to make certain that water is flowing from the solenoid valve into the distributor pan. Do not lift the cover off the cabinet more than 1 in. when water is flowing. See Fig. 6 or 7, according to the model you own. SOLENOID VALVE DISTRIBUTOR COVER DISTRIBUTOR PAN EVAPORATOR PAD CABINET BOTTOM ACCESS PANEL MODEL 49BF 6 • On a Model 49BG humidifier, gently pûll the latch that secures the access door. Lift the door about 1 in. Check to see if water is flowing from the solenoid valve into the distributor pan. See Fig. 8. • If your humidifier is a Model 49WS unit, look through the window on front of the unit to see that the evaporator pad is rotating and water is flowing. See Fig. 9. 4. Turn OFF the furnace. When the blower stops, look into the humidifier to make sure the water is not flowing into the unit. NOTE: The Model 49WS is controlled by a float valve. Turning off the furnace will not affect the water flow until maximum heater level is achieved. 5. Replace the cover assembly and fasten securely. 6. Now, turn the furnace ON and set the thermostat for desired room temperature. SHUTDOWN PROCEDURES To shut down your humidifier, simply close the saddle valve on the water line. Then turn OFF the humidistat. When set to the OFF position, the humidistat shuts off the electrical power to the solenoid valve and/or motor on the humidifier. NOTE: If your home comfort system includes cooling, be 3 sure the water supply to your humidifier is turned off during the cooling season. Close the damper located in the bypass duct if one is installed. If your humidifier is a Model 49WS, drain and clean the water pan as described under cleaning procedures. PERFORMING ROUTINE MAINTENANCE With the proper maintenance and care, your humidifier will operate economically and dependably. Maintenance can be accomplished easily by referring to the following directions. However, before performing any maintenance, consider these important safety precautions: A WARNING DISCONNECT ALL ELECTRICAL POWER TO THE HUMIDIFIER AND FURNACE BEFORE PERFORMING ANY SERVICE OR MAINTENANCE. A FAILURE TO FOLLOW THIS WARNING COULD RESULT IN PERSONAL INJURY OR DEATH. A87137 NOTE: THERE MAY BE MORE THAN ONE ELECTRICAL DISCONNECT SWITCH. • ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO MINIMIZE SHARP EDGES IN THE CONSTRUCTION OF YOUR HUMIDIFIER, BE EXTREMELY CAREFUL WHEN HANDLING PARTS OR REACHING INTO THE UNIT TO AVOID PERSONAL INJURY. Your humidifier has been designed for easy disassembly. This simplifies cleaning and servicing. Your unit must be kept clean to maintain its efficiency. Regular inspection allows you to determine the cleaning schedule best suited to your humidifier’s operating conditions. The frequency for required maintenance will depend most upon the available water supply. In areas where hard water and high mineral content are prevalent, a humidifier requires cleaning and servicing more often than one supplied with softer water. At minimum, the humidifier will need to be cleaned at the beginning of every heating season. CLEANING PROCEDURES Models 49BF, 49BG, and 49FH 1. Turn OFF all electrical power to the humidifier and furnace. See Fig. 11. 2. Turn OFF the humidifier’s water supply. See Fig. 4. 3. Disassemble the humidifier.
